TRANSMISSION BAND.

Application filed July 5, 1922. Serial No. 572,991.

To [ZZZ whom it may concern: 7

Be it known that I, MURRAY L. BRUCE, a. citizen of the United States of America, and a resident of Milan, in the county of Ripley and State of Indiana, have invented a new and useful Improvement in a Transmission Band, of which the following is a specification.

My invention relates to the type of transmission band that is used onautomobiles.

An object of my invention is to provide a band of the type referred to, which may be *asily, conveniently and quickly mounted about the transmission drum of motor veliicle.

Another object of my invention is to provide a band which may be readily removed from the casing surrounding the transmission drum without dismantling the entire casing.

These and other objects are attained by means described herein and disclosed in the accompanying drawing, in which:

Fig. 1 is a perspective view of a band bodying my invention.

Fig. 2 is an enlarged tragmental sectional view of the band shown in rig. 1.

The circular band 3 comprises a single integral strip. The ends t 5 of the band have substantially U shaped formed in them, the base of the taped slit extending transversely of the band, anl the branches of the slits extending substantially parallel with the side cdges'ot band, away from the ends of the band carrying said slits. The material which severed along three of its sides by the provision of the slits, is turned outwardly of the band and extends away from th l of the baud carrying the slits defining tuc respective severed material. This m e ial *Fca'ms lugs 6. 7. and 9. The inner in 12g '10 of the band worries suitable lining material 11, it? and 13. The sections of liningare spaced at their ends whereby to provide ducts extending transversely to the lining and the band. The lining see ments are mounted on the band in. any suitable manner such as by means of the two prongecl rivets l5. Lars l6 and 17 are mounted upon the e and 5 respectively of the band. The ave formed in them form on the formed on it a yoke-like projection 19 between the arms 20 and 21 of which a coupling bolt 22 may extend. The coupling bolt carries the usual spring 23 and nut 24, and is adapted to be connected with suitable control levers as is connnon in the art. The pairs of lugs on theends at the band are spaced at such distance that each of the lugs may be inserted thi'u an individual slot 18 in one of the ears. and the free ends of the lugs are spaced from the band at a distance substantially equal to the thickness of the ears immediately to the rear and adjacent of the slots 18 in the ears.

The ears are mounted on the band by passing the lugs thru the slots in the ears, and then movingthe ears rotatively about the band in directions opposite to those in which the lugs engaging the respective ears extend. The relative movements of the band and ears are continued until the rear walls of the several slots .8 engage. the respective lug extending thru said slots. at the forward or upper ends of the lugs, in other words, at those places where the lugs adjoin the band. In order to remove the ears from the band, the proceeding is reversed. When it is desired to remove a band embodying: my invention from about the drum upon which the band is adapted to operate, either or both of the cars will be removed from the band and the band may then be rotatably actuated in order to separate the band the drum.

lt. should he observed that by the cars are mounted, con parts of the band and are struck from the band that lining and upon the hand its ardire the mounting: of the ears upon the band. It should also be observed that the band comprises a single metallic strap, whereby there no danger of separation of parts as is common in transmission ban-is made of sex-oral hingedly connected part;

hat .l claim is:

A transmissitm band of the class described comprising a single circul; r mctallicband havingsubstantially U shaped lugs struck outwardly there from adjacent the ends thereof, the lugs being turned upon the band and extending away from the respective ends of the band carrying said lugs, and ears detechahly mounted ends of the v leopband having slots adapted to accommodate the lugs, the ears in mounted positions having one of the Walls of each of the slots ;in

engagement. with :1 lug on the hand, the

Walls of the slots in the ears engaging the lugs being disposed farthest froin the end of the band carrying said ear, snld Walls of In testimony whereof, I have hereunto subscribed yny name this 30th day of June, 1922.

MURRAY L. BRUCE.
